Provided are a computer readable recording medium with a computer program and an executing apparatus thereof. The computer program of the recording medium quickly and accurately estimates a gene which causes a hereditary skeletal muscle channelopathy by performing a method for estimating the cause of the hereditary skeletal muscle channelopathy to determine the gene which causes the hereditary skeletal muscle channelopathy using information about episodic paralysis and myotonia. Thereby, a user quickly grasps the cause of the hereditary skeletal muscle channelopathy with low costs by testing a part of various genes which cause diseases. [Reference numerals] (AA) Start; (BB) End; (S110) Select at least one among episodic paralysis and myotonia; (S120) Input first symptom information corresponding to the episodic paralysis if the episodic paralysis is selected; (S130) Input second symptom information corresponding to the myotonia if the myotonia is selected; (S140) Determine the gene which causes the hereditary skeletal muscle channelopathy using the first and second symptom information; (S150) Display the gene which causes the hereditary skeletal muscle channelopathy on a screen
